I just wanted to post an update that my kits is growing mushrooms. I have around 8 or so sprouting in the first flush of growth, pretty exciting.

Thanks for the update Brandon. I have not grown portabello mushrooms before but I really enjoy fresh home grown mushrooms. I'd be interested to know how long your harvest lasts and the conditions ( water, humidity, temp. etc ... ) that you are keeping them.

I got the mushroom kit for christmas. Its suppose to produce mushrooms for up to 3 monthes. The kit is just a small cardboard box maybe 10x14. Its got the spores in it in one bag and another bag of compost/wood chips. You just mix all the stuff together and and water. The temp requirements are 60-75 degrees in a low light level area. Our first crop was around 8 portabellas that were around 3 in in diameter. Its suppose to produce a new crop every 2 weeks or so. I dont know if the kit it worth the cost of just going out and buying your own mushrooms but this was a gift for christmas. So if ya get one good luck.

Might work because I had a mushroom kit (I am a mushroom expert myself) And it lasted for a year. Not saying all mushroom kits last as long though. There might be a chance, though.
